Football-shaped building unit



FIG. 1 is a front elevation view of my design.

FIG. 2 is a rear elevation view of the design shown in FIG. 1.

FIG. 3 is a top plan view of the design shown in FIG. 1; and,

FIG. 4 is a side elevation view of the design shown in FIG. 1.

The broken lines are for illustrative purposes only, and form no part of the claimed design.

The side view opposite FIG. 4 is a mirror image of FIG. 4, respectively.

The bottom view of the design is not visible in its normal or intended use because it is substantially obscured by the ground. Therefore, the bottom view is not a matter of ornamental concern, and has been omitted from the drawings. 

I claim the ornamental design for a football-shaped building unit, as shown and described.
